SASH-BALANCE.

SPECIFICATION formingpart of Letters Patent No. 519,895, dated May 15,1894.

Application filed August 21, 1893.

T at whom it may concern.-

Be it known that I, DAVID SINKs, of the city of Belleville, St. Claircounty, State of Illinois, have invented certain new and usefulImprovements in Sash-Balances, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to an improved sash balance, and consists in thenovel arrangement, combination and construction of parts, as will bemore fully hereinafter described and designated in the claims.

In the drawings: Figure 1 is a perspective view of the window showing myinvention applied thereto. Fig. 2 is a side elevation of a horizontaladjustable bar showing its connection with a rope which I use incarrying out my invention. Fig.3 is a plan view of a pulley and itsbearings which I use in carrying out my invention. Fig. 4 is a sideelevation of the parts shown in Fig. 3. Fig. 5 isa vertical section of awindow-frame and another pulley which I use in carrying out myinvention. Fig. 6 is a vertical section taken on the line 6-6 of Fig. 5.Fig. 7 is a front elevation of a plate which I use in carrying out myinvention. Fig. 8 is a vertical section through a portion of awindow-sash and the plate which is shown in Fig. 7.

1 indicates a window-frame which is constructed with the usualjamb-casings 2 which are provided with the usual guide-ways or stops forthe sashes 3 ands. This frame is also provided with a headcasing 5.

6 indicates a plate which is located on the sash 3 adjacent its uppercorner and is held in position by being screwed thereto by screws 7passing through apertures 8, there being two of these plates locatedsubstantially the same, one not being shown. Formed through this plateis a vertical slot 9, the lower end of which is provided with an en--larged portion 10.

11 indicates a cut away portion which is formed in the sash 3immediately back of the openings 9 and 10 of the plate 6.

12 indicates a pulley which is mounted in bearings 13 and locatedadjacent the bottom corner of the sash 4, there being two of these, onelocated at each corner thereof. r

Serial No. 483,685. (No model.)

' Located on the bottom side of the head casing 5 and in alignment withthe plate 6 is a pulley 14 which is provided with bearings 15 which areconnected to said casing. Formed in said casing to allow room for thepulley 14 is an opening 16 which allows the pulley to be partly sunkenin said casing.

17 indicates a horizontal tube located as shown in Fig. 1, one end ofwhich is closed and provided with a horizontal U-shaped bar 18 connectedthereto the ends being bent so as to form eyes 19. Located in the eyes19 is a vertical bar 20 bent so as to form a ring 21 intermediate of itsends and located between the eyes 19. Formed on each end of the verticalbar 20 is an eye 22.

23 indicates a horizontal bar located in the tube 17 and held inposition by the thumb screws 24. The outer projecting end of thehorizontal bar 23 is provided with a horizontal U-shaped bar, this barbeing the same in construction as the U-shaped bar 18 and bethenceupward through the eyes 22 of the aforesaid bar and thence upward overthe pulley 14 and thence downward and is connected to the plate 6 by aknot being formed on the end thereof and passes through the opening 10in said plate. The slot 9 opening into said opening isso constructedthat when the rope is slipped into said slot it will retain said rope inthe required position. There being two of these ropes, one located ateach side of the sashes 3 and 1, they both being the samein connection Iwill omit the other one.

The operation is as follows: The sash being of the same heft they willbalance each other and stay in whatever position the operator placesthem. By raising the bottom sash the top sash being swung on the ropes25 it will tions at the ends thereof readily permit this operation,which can be readily seen by inspecting Fig. 2. By slipping this bardown it lengthens the ropes 25 and the top sash will gravitate down thesame distance the ropes have been lengthened. The horizontal bar 23being adj ustably located in the horizontal tube 17 it can be readilyadjusted lengthwise to conform with different sizes of windows. When itis so adjusted they can be made rigid with each other by the thumb screw23 threaded through the tube 17 and engaging the bar 23.

What I claim is- 1. A sash balance and operator consisting of ahorizontal adjustable bar constructed of a tube, a bar located in saidtube constructed to horizontally move therein, horizontal U- shaped barsconnected to the ends thereof, vertical bars located in eyes formed onthe ends of the U shaped bars, said .bars bent so as to form a ringintermediate of its ends and located between the ends of the U-shapedbars, a rope connected to the sash, and eyes formed on the ends of saidvertical bars, and constructed to vertically slide on said rope,substantially as set forth.

2. In combination with a window operating device, a horizontal tube, abar adjustahly mounted in said tube, means for holding said 0 bar andsaid tube rigid with each other, horizontal U-shaped bars connected tothe opposite ends thereof, vertical bars connected to the end of theU-shaped bars and means for adjustably connecting said bars with ropessubstantially as set forth.

3. A device for operating window sashes consisting of ropes 25 the upperends being detachably connected to the upper sash by a plate 6, saidropes passing over pulleys 14 connected to the head casing of the windowframe, thence downward through eyes 22 over pulleys 12 located on thebottom sash, and thence upward and knotted to a ring 21 formed on thebar 20 carrying the eyes 22, U-shaped bars 18 connected to the bars 20,a horizontal tube 17 one end of which is connected to one of theU-shaped bars 18, a

horizontal bar one end of which is connected to the other U-shaped bar18 and adj us'tably mounted in the tube 17, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
